It's TSMC N6. What does that information benefit you? We're still talking about a boutique chip that's not going to outperform anything from the past decade's worth of amd64 products.
Because process affects performance per watt more than architecture so its a useful data point.
Even knowing nothing about performance, knowing that it is N6 means it probably isnt particularly power efficient (as compared to leading edge x86/ARM).
That chip is actually reasonably power efficient, not very far away from leading edge x86 assuming 180W TDP. At 120W, the RISC-V server is on par or even exceeds the power efficiency of the x86 system.
Yep, you compare chips on the same level of silicon process.
I was curious to see how far RISC-V still have to go from a microarchitecture stand point, but even in the same silicon process level, there are other things to take into account: the RISC-V compiler support, and something which is really new: since RISC-V is a non-IP-lock worldwide standard, assembly writting is much more a reasonable thing.
And not just the same level of silicon process, as with a reference point, it is possible to further extrapolate using knowledge of differences between process nodes.

According to that graph, the P870 has 80% of the performance of Ice Lake.
We can compare performance with other TSMC N6 designs. Even more so if we also know the area and power.
This isn't some U74. This is P870. Its published performance data is no joke.

Knowing it is TSMC N6 unlocks at least this much.
